Question

10. How many cubic inches of material do you need to make a solid rubber ball with a diameter of 3 in.? Round your answer to two decimal places.

Answer 1

Answer:

14.14 cu in.

Step-by-step explanation:

Answer 2

What is asked in the problem is simply the volume of the solid rubber ball. The volume of sphere given the diameter may be calculated by,
  
                               V = πd^3 / 6

Substituting the given value of diameter, 
 
                               V = (π x 3³) / 6 = 9π/2 or 14.14

Thus, one needs approximately 14.14 in³ of material.
